Wayne, your camshaft specs looked very familiar to me and I dug out my old cam card for the last 540 CID I built and it looks like we have the exact same camshaft! I agree about being a bit on the tame side for such large displacements but I was content leaving a little power on the table for the sake of valvetrain reliability. I've known too many people that built "big" motors and cam'ed them to the point where they were just valvespring killers and I wanted to avoid that. And yeah, you're right about Dynatech also making a Tall-Deck header for Camaros/Novas for about $770. I'd probably order a set each....both Dynatech and Doug's, check 'em out in person and keep the set that I like the most and return the others. Hook these up to a TorqueTech 3 1/2 exhaust system and you've got a neat set-up. Hey, about an old Edelbrock C454 dual-plane with a Holley 4500 hidden under a stock type air cleaner? That be a great set-up for the top of a big motor and look "stock-ish".
